“ In fact, DuckDuckGo gets its results from over four hundred sources. These include hundreds of vertical sources delivering niche Instant Answers, DuckDuckBot (our crawler) and crowd-sourced sites (like Wikipedia, stored in our answer indexes). We also of course have more traditional links in the search results, which we also source from a variety of partners, including Verizon Media (formerly Yahoo) and Bing.”
It is not false. The standard 10 links you see come directly from Bing and they don’t even attempt to hide that fact.
I've seen logs of a few medium sized sites and I've never seen DuckDuckBot really crawling any of these sites. I'm sure they use their own results to supplement some parts but most of the web results still seem to come from Bing.
I've switched to Bing for images (more filters and less safe-search) and recipes (so many options!) , but for general search I find their index to be smaller and their results less relevant than Google's.
Any takers for trying out Bing?
